Ebay is a bellwether. It's been around since nearly the start of the online boom. But, like any other platform, success can seem fleeting if you don't know what you're doing. Selling items on eBay, professionally that is, can be an art form. Getting people interested in your auctions isn't always easy, especially when there's hefty competition and low demand for what you're selling.
Posting ads on Craigslist is technically easy, but people often have fears about posting their personal information on the site. I communicate mostly through email when doing business on Craigslist, and I’ve never run into any issues. I’ve never been ripped off, nor have I been murdered or raped for using the site. It takes common sense, so use your best judgment, but don’t assume someone is a thief just because of their preferred communication method. For an extra bonus, google “funny Craigslist ads” to see some delightful examples of guerilla and grassroots marketing.
Grow plants, herbs, or vegetables to sell if you have a green thumb. If your parents let you plant your own garden in the backyard, opt for easy-to-grow vegetables like lettuce, tomatoes, or cucumbers. If you will be growing your plants inside in pots, choose ones that don’t require a lot of sunlight or space. Pick your vegetables when they’re ripe and sell them in bags or plastic containers.
